Communicating with the rear end of the open- Fig. 2 vis a vertical section taken approximately ing 17, is one end of a flushing water pipe `21 on the line 2-2 of Fig. 1. that leads through the upper portion of plate l0 llo 13 immediately below said opening is a relativelyY small chamber 25.

Leading downwardly from the lower portion of opening 17, through the sides or" the body 13, are ducts 26 that communicate with the sides of chamber 25.

Formed through the wall between chamber 25 and outlet opening 24, are openings 27 that are inclined so that they may direct jets of water upwardly and rearwardly from the lower portion of opening 24 through the rear end thereof.

Formed integral with plate 10 and positioned within chamber 14 is a housing 28 within which is formed a spirally disposed siphon chamber 29, the same occupying a plane substantially parallel with plate 10 and therefore at right angles to the major axis of the bowl 12.

The inner lower end of the housing 28 projects a short distance horizontally and said end is provided with a flange that surrounds the corresponding end of the spiral Siphon chamber 29 and this flange is secured in any suitable manner, preferably by means of Studs and nuts to the rear lower face of the body 13 so that the lower inner end of the siphon chamber 29 communicates directly with the rear end of discharge opening 24 (see Fig. 2). This joint between the siphon housing 28 and body 13 may be packed or calked in any suitable and wellknown mannerto form a watertight joint.

The outer end portion of the Siphon housing 2S is formed integral with and extends through plate 10, thence downwardly and the lower end ci said housing is suitably connected behind plate 10 to a waste or outlet pipe 39 that leads to the sewer or other outlet. Y Y

Formed in the upper portion of siphon housing 28 is an openingthat is normally closed by a normally removable plug 31, thereby permitting ready access to the siphon chamber 29 for the purpose of cleaning the same or removing obstacles therefrom.

Y Leading from the rear portion of the chamber within bowl 12, just above the forward end of outlet opening 24, is a vent duct 32 that leads upwardly rearwardly through the body 13 and the upper rear end of this duct communicates with a tube 33 and the latter being connected to the top of the siphon housing 28 and communicating with the top of the chamber 29 therein. This ent duct and tube provide means for breaking the siphon within the chamber 29 when the water lever lowers to a predetermined point within bowl 12. Y

Formed in the side wall of the bowl 12, just below the ilushing water duct 18, is a series of apertures 34 that communicate with a duct 35, that is formed through the wall of said bowl and through body 13 and the rear end of this duct communicates with a tube 36 that leads rearwardly through chamber 14, thence through plate 10, thence downwardly and the lower end of said tube communicates with the pipe through the lower portion of the housing 28.

These apertures 34, duct 35 and pipe 36 function as an overiiow to permit the escape of water from the bowl in the event that an obstruction or clogging should cause the water within said bowl to rise to an abnormal level. Pipe 36 is provided within chamber 14 with a trap 37 to prevent backilow of gas or foul air from the waste pipe 30 to the interior of the bowl.

a certain amount of fresh water will pass through the overflow outlet connection.

Under normal conditions the level of the body of water in the lower portion of bowl l2 is above the lower end of duct 32 and this level extends to the top of the partition within the Siphon chamber 29.

When knob of handle 23 is actuated to open ilush valve 22, water will iiow from supply pipe 21 through opening 17, thence through duct 18 and thence through outlet openings 19 downwardly into the chamber within bowl 12.

A certain amount o1" water discharging into opening 17 will iow downwardly through ducts 26 into chamber 25 and this water will discharge in jet form upwardly and rearwardly into the lower portion of the siphon chamber 29, thereby tending to accelerate the how of the body of water from the bowl into the siphon chamber and thereby quickly ll said chamber so as to establish siphonic action.

The suction siphomc action in chamber 29 will quickly draw water from the bowl 12 through outlet 24, thence.

through the siphon chamber and said water will discharge downwardly through the waste or outlet pipe 30.

As soon as the water level in bowl 12 passes below the lower end of duct 33, the siphonv within chamber 29 will be broken, with the result that the suction of the water within bowl 12 will cease and said bowl will rell to its normal level by water that enters the bowl through supply pipe 20 and flush valve 22, which latter automatically closes after a predetermined iiushing period.

As heretofore stated, all danger of overilowing of the water that discharges into the bowl is eliminated by the provision of the overow connections 34, 35 and 36 and each time the bowl is flushed a certain amount of fresh water will discharge through the overflow connection from jet opening 38.

Plate 10 is rigidly secured to the wall structure and preferably the studs therein by means of bolts and said plate rests directly upon the iloor, thereby providing a very strong and substantial support for the bowl so that it is not necessary to support the outer portion of the latter from the door.

Plate 10 may be secured to the wall structures or studs so as to hold the bowl 12 at any desired elevation and in this connection it may be stated that it is the present practice of architects and builders to follow the suggestion of health authorities and physicians to arrange the bowls so that the seats on the tops thereof are considerably lower than the toilet bowls heretofore installed.

In the modied form of bowl illustrated in Figs. 6 to 11 inclusive, the construction of the bowl is very similar to the construction heretofore described with the exception that the chamber 14 in the rearwardly extending body or" the bowl is eliminated and the spirally formed housing 28a that contains the siphon chamber, is formed integral with the rear side of a plate lof1L and which latter is directly connected by means of bolts 112i to the body 13a wardly from bowl 12a. Y

Plate 102 which is secured to the wall structure in any suitable manner, extends a short distance above the body 13"L and formed in this upwardly projecting portion is an opening 10b that is normally closed by a removable plate 10c, thereby giving access to the interior of the wall structure and the parts that are located therein.

A packing ring or gasket is located between the rear face of the body 13a and plate l()a around the outlet opening 24a in the lower portion of the bowl and around the opening into the Siphon chamber 29:i in housing 28a.

In this modified construction, a flush water supply pipe 2la provided with a flush valve 22e, leads to opening 17a that discharges into flushing duet 18a and leading from the rear portion of the chamber within the bowl below the normal water level upwardly and rearwardly to the top of the siphon chamber 29a, is a duct 32a that admits air to the siphon chamber when the water level in the bowl lowers to a point below the inlet end oi said duct.

This form of bowl is also provided with a chamber 25a in the lower portion of the bowl and leading thereto from inlet opening 17a, are duets 26a.

Inclined jet openings 27e lead from the rear portion of chamber 25 and are adapted to direct jets of water upwardly and rearwardly into the intake end of the siphon chamber 29a, the same as the jet openings 2'7 heretofore described.

Thus it will be seen that we have provided a toilet bowl that is relatively simple in construction, inexpensive of manufacture and very eiective in performing the functions for which it is intended.

Installation of the bowl can be effected between 16 inch center studs in a 6 inch wall and connections made to the sewer or outlet pipe without resorting to the usual cutting of studs and floor joists which practice is necessary with bowls of that projects rearthe present construction and materially weakens the building structure.

The chamber 14 in the rear portion of the bowl enables the siphon and other parts of the structure to be easily reached for the purpose oi' inspection, repairs and replacements and in the event that the outlet 24 or siphon chamber becomes clogged, the cleanout plug 31 may be readily removed to give access to the Siphon chamber and permit the ready removal of the obstruction.

The plate 1 0, with the siphon housing and associated parts may be used in connection with urinals, bathtubs, laundry trays, wash bowls, kitchen sinks and like structures for the purpose of effecting a discharge of the water from the trays, bowls and other containers, in much less time than is required by the generally used gravity and trap methods and at the same time producing a larger and better water seal for protection against sewer gases.
